ISAAC H. UPTON, OF N-EW YORK, N. Y.

FIRE-PLACE.

Specification forming part of Letters Patent No. 59,484, dated November6, 1866.

To all whom it may concern: y

Be it known that I, IsAAc H. UProN, of the city, county, and State ofNew York, have invented a new and useful Improvement in Fire-Places forGrates; and I do hereby declare the following to be a full, clear, andexact description of the nature, construction, and operation of thesame, reference being had to the accompanying drawings, which are made apart of this specification, and in which- Figure l is a plan or top viewof a replace illustrating my invention. Fig. 2 is a front elevation ofthe same. Fig. 3 is a vertical section from front to rear, the line .frindicating the plane of section. Fig. 4 is a vertical central sectionfrom front to rear, as indicated by the line y y.

Similar letters of reference indicate corresponding parts in the severalfigures.

The subject of this invention is a fire-place for a grate; and theimprovement consists in the method of surrounding the chamber whichcontains the grate with an air-heating chamber, which receives cool airthrough the lower part of the perforated front or frame-work, around thefront of the fire-place, and discharges the same in a heated conditionat the upper part 0f said perforated frame-work, or into suitable pipeswhich may be employed to conduct it into other apartments of thebuildlng.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe it in detail, with reference to the accompanying drawings.

A represents the iron grate, which may be constructed in customarymanner, and supportedat a suitable height above the hearth or floor uponanges C', which may be formed for this purpose at the lower terminationof the walls of the chamber B. The walls ofthe chamber B are joined tothe iron-work C, to which the front of the grate is attached, and saidchamber is provided with a back plate, D, which, as clearly shown inFig. 4., stands some distance in front of and away from the rear wall ofthe chimney, so as to leave a space, E, which is but a continuation orportion of the space or chamber which surrounds the top, bottom, sides,and back of the gratechamber B.

F is a plate extending in an inclined position entirely across the lowerpart o f the chimney-flue, and employed to close the communication ofsaid flue with the .space E, and with the grate-chamber B when desired.

H is a short pipe or flue leading from the interior of the grate-chamberinto the iiue G. This pipe may be opened or closed at will by means ofthe damper I, which is operated by means of the rod l, extending throughthe front C of the grate.

The inclined plate F is provided with two similar dampers or valves, JJ, and rods J J', the latter also extending through the front of thegrate, to enable valves J J to be opened or closed, as may be desired.

The upper portions of the sides and back of the chamber B may convergetoward the top, for the purpose of affording sufficient space betweensaid chamber and the surrounding parts.

The back D may be cast entire with the walls of the chamber B, or it maybe of sheet-iron and riveted upon the same. The metallic.

lining K of the rear wall of the chimney can be used or dispensed with,as preferred.

L L are two oblong perforated plates, standing vertically behind and atthe opposite sides ofthe front C, and joined edgewise to the latter. Lis a similar perforated plate, supported upon the upper edges of thefront G and the vertical plates L L. The front C and plates L L L formthat part of the iron-work of the` grate which projects into the room.

From the above description of the construction of my improvement theoperation will be readily understood. When the valves J J are closed,air enters the chamber or space E through the lower part of theperforated. plates, and, after circulating in contact with the heatedsides and back of the chamber B, passes into the room through the upperportions of the plates L L, or through the 'upper perforated plate L. lfdesired, however, the air thus heated in the chamber E may be conductedthrough pipes to other apartments of the house. It

will be seen that while the gratefchamber B may be made to communicatewith ue G by -opening the valve I, communication may be closed betweenthe air-heating chamber E and flue G by means of the valves J J. Hence afull draft may exist and the effective heat of the grate be retained andutilized at the same time. The heat may, however, be moderated orpermitted to escape by means of the valves J J, to suit the occasion.

Having thus described my invention, the following is what I claim `asnew herein and desire to secure by Letters Patent:

l. The inclined plate F, in combination with valves or dampers J J androds J J employed to retain or permit the escape of heat, and arrangedas and for the purpose specied.

2. In combination with the above, the airheating space or chamber E,formed and arranged substantially as and for the purpose set forth.

M. rival n" 3. In a fire-place for grates constructed as hereindescribed, the perforated plates L L L',

arranged as described, and permitting a free I. H. UPTON.
